GRAIN- SPECIFICATION forming part of Letters Patent N o. 271,957, datedFebruary 6,

DOOR.

`Application tiled J une 28, 1882. (No Inodel.)

To all whom it may concern:

Be it known that I, ROBERT J. WALKER, of Girard, in the county ofMacoupin and State of Illinois, have invented a new and ImprovedGrain-Door, of which the following is a full, clear, and exactdescription. y 4

My invention relates to improvements in doors for grain-cars; and itconsists in a door hinged to a swinging plate to adapt it to be swungupward edgewise and against the side `of the car when not in use; and italso consists in the peculiar construction and varran gement of parts,as hereinafter fully. described,mh

and pointed out in the claims.

Reference is to be had to tbe accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both thegures.

Figure l is a perspective view of a portion ofthe inside of a car-bodyhaving my improved grain-door applied to it, and Fig. 2 is an exteriorside elevation of the door.

I make the door in two parts, a and b, which l hinge together by insidehinges, o, preferring to groove the edge of one part, as at d, and tocorrespondingly curve the edge of the other` part to lit closelyin thegroove and makeatight joint, although square edges may be employed.Inside of the door-jainb I hinge the part a of the door, by a pivot, e,at the top, in a plate, f, which isalso pivoted at g in the top of thepost h and in the door-jamb. The lower end of the door has a similarpivot, i, lodged in a slot,j. Both of these pivots e and t' are locateda-suitable distance from the `edge lc to allow itto swing into a groove,l, in the side of post h, said edge k being curved to iit snugly in thegroove, which is to be correspondinglyformed. 'The pivot gis to beslightly lower than the top of the door, so as to cause the hinge-platefto draw the door down tightly on the floor. The edge m of doorb isslightly curved to swing into a correspondingly-curved groove in thepost n, and the top of said groove is beveled at o, so that the beveledcorner p of the door will be borne down tightly on the door.

The door is fastened'shut by the hasp g and pin ton the outside. Ifdesired, the slot j in the oor for the pivot i may be elongated andsuitably sloped on the bottom to allow the door to swing upon the pivotg into the position represented by the dotted lines and lodged on thehookstud u when the door is not required to be shut.

I am aware that car-doors made in two parts and hinged together havebeen secured to sliding hinges; and I am also aware tbatdoors hingedtogether and sliding in ways of the door-jamb are old, and I thereforedo not claim such invention.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A car-door hinged to a swinging plate,substantially as herein shown and described, whereby the door is adaptedto be swung upward edgewise and against the side of the car when not inuse, asset forth.

2. The combination of the grooved posts h and n Vwith the door made intwo parts, a and b, and hinged together, and also hinged to the interiorof the door-jamb, substantially as described.

3. The pivots c andi, arranged with respect to edge la ot' the door,.andthe grooved post h to enable said edge k to swing into the groove of thepost, substantially as described.

4. The door a b, hinged to post h by pivot e, and hinge-platef, saidplatef being pivoted to the post and doorjamb,substantially asdescribed.

5. The door ab, hinged to post h, and pivoted in the slotyl on the door,substantially as described.

6. The door a b, arranged in the slot j, and on the pivot, substantiallyas described,'for lodgment on the stud-hook u, substantially as specied.

7. The hinge-platef, arranged with respect to post h and door a forbearing said door on the floor, substantially as described.
